TRX® 2.5 Racing Engine, Where Power Meets Technology®
"The TRX 2.5 blows away every other small block engine we've ever tested!" —R/C Nitro Magazine
"Best Nitro Engine" —RC Car Action Magazine Readers' Choice Award
The TRX 2.5 Racing Engine is nothing short of amazing. It comes loaded with all the hottest performance goodies. The two-needle composite slide carburetor, trick porting, and free-flowing rear exhaust deliver unmatched, class-leading horsepower that rips huge wheelies and pushes the T-Maxx past 40mph! Plus only the TRX 2.5 has the push-button starting convenience of the EZ-Start® Electric Starting System.
High-Volume Air Intake System
The TRX 2.5 Racing Engine uses a high-volume air intake system with a two-stage air filter. The filter housing and neck are designed to mate seamlessly with the carburetor to eliminate turbulence in the air-flow going into the engine.
Tuned Exhaust System
Call it a factory 'works' pipe. The header and pipe length and shape are dyno-tuned for the TRX 2.5 to bring out the most power over the broadest RPM range. All that means is you can nail the throttle hard at any speed and get some serious 4-wheel roost.
EZ-Start® Electric Starting System
The Traxxas EZ-Start consists of an onboard drive unit that lights the glow plug and spins the engine for easy push-button starting from the handheld control module. The controller contains diagnostic LEDs that provide real-time status of the glow plug and starter motor. It tells you if the glow plug is bad and protects the starter motor from overloading. The EZ-Start system is powered by a standard rechargeable 7.2 volt battery pack. Once you've used the EZ-Start system, you may never go back to pull-starters again!
Precision 2.4GHz Control
With the TQ 2.4GHz radio system, you just switch on and drive. There are no channels or frequencies to manage, so the focus is on having fun. The TQ's ergonomic design is comfortable for all-day driving, and its sleek lines are enhanced by an internal antenna that is impervious to damage. To customize the controls, the transmitter's factory servo directions can be easily reversed using the TQ's simple programming system.
Forward/Reverse Two-Speed Transmission
T-Maxx's fully enclosed transmission features two-speeds forward and two-speeds reverse with a speed-sensitive reverse lockout. It provides racing-truck acceleration in low gear and 40+mph top speeds in high gear. Shifting is hard, fast, and automatic with an adjustable shift point! Just push a button on the TQ-3 transmitter to shift into reverse. Only the patented T-Maxx design allows full proportional control of throttle and braking, along with two-speed shifting, in both forward and reverse gears (patent# 6367345).
Adjustable Slipper Clutch
T-Maxx is equipped with an adjustable slipper clutch to absorb drivetrain shocks and protect against damage, especially after those 30-foot jumps you just couldn't resist. Standard spur gears are used to allow easy changes to the overall gearing.
T-Maxx uses a disc brake mounted forward of the transmission to provide powerful 4-wheel braking action and sure-footed stopping power. A fiberglass-composite disc and stainless steel pads are used for long life and reliability.
U-Joint Slider Driveshafts
The large diameter slider driveshafts are made to take abuse. With real u-joints at each end and variable-length sliding half shafts, our driveshafts allow longer suspension travel, no binding, and less friction than metal 'dog-bone' shafts. The Traxxas driveshaft material absorbs impacts and stress loads that break skinny metal drive shafts. It's a superior, better-engineered solution.
The differential case is strengthened for more precise gear alignment. Hardened-steel ring and pinion gears have been precisely engineered to deliver quiet, efficient operation and reliable performance. The integrated planetary gear differentials also use hardened steel gears for tough, virtually maintenance-free running. They're made to take the rigorous off-road pounding that comes so naturally for a T-Maxx.
High-Torque Steering Servo
A big truck needs a powerful steering servo for responsive performance. The included Traxxas high-torque servo delivers over 80 in/oz of torque.
Bellcrank Steering System
The bellcrank steering system provides precise steering geometry for correct Ackerman and almost no bump steer, even with T-Maxx's huge suspension travel. The supplied bellcrank bushings can replaced with ball-bearings for even smoother steering performance.
That Famous Maxx® Suspension
One of the hallmarks of the T-Maxx is its incredible WideMaxx 4-wheel independent suspension. Wicked long travel, nearly 4 inches at each wheel, is ready to take on just about the roughest terrain you can imagine. Eight oil-filled shocks (two at each wheel) deliver that plush feel and 'bottomless' suspension travel T-Maxx is famous for. The WideMaxx is fully tuneable for the track with up to 10 shock-mounting positions, adjustable front caster angle, front and rear toe, and front and rear camber angles.
Oil-Filled Ultra Shocks™
Traxxas oil-filled Ultra Shocks are fully tuneable for race-inspired performance. The spring pre-load is adjustable via precise clip-on spacers making it easy to know that each shock is adjusted to the same spec. Rubber pressure bladders prevent air pockets and foaming common with bladderless designs. Double o-ring seals in the shock body prevent leaking.
6061-T6 Aluminum Chassis
The 3.2mm aluminum chassis is formed from durable 6061-T6 aluminum and then anodized in beautiful blue. Besides forming a rigid backbone for the rest of the truck, the aluminum acts like a heat sink to draw additional heat away from the engine. All of the systems and components are neatly arranged on the chassis for easy cleaning and servicing.
High Ground Clearance
The unique T-Maxx chassis design offers maximum center ground clearance (over 4 inches) to eliminate the high-centering and chassis dragging that plague flat-chassis monster trucks. Plus it maintains that tall, authentic monster truck look.
ProGraphix® Painted Body
The extended wheelbase T-Maxx body comes fully trimmed and painted. Decals are also applied to save time and get you driving just minutes out of the box. Traxxas' ProGraphix bodies are the hottest looking bodies around and are only available on Traxxas Ready-to-Race® models. Available in red, blue, black, and white.
Rubber-Sealed Ball Bearings
Nothing less than the precision of smooth-running ball bearings is good enough for T-Maxx. Faster performance, less maintenance, and no need to plan for a costly upgrade are just a few of the benefits.
Pre-Glued Wheels and Tires
The wheels are molded from durable nylon and carefully engineered be strong with the least amount of weight. The monster 5.75"h x 3.5"w tires use foam inserts so that the tire carcass can be thinner and lighter. The wheels feature a metalized finish that provides the realistic look of real aluminum without the weight. It all adds up to lower rotating mass and quicker acceleration.
Heavy-Duty Nylon Construction
The T-Maxx isn't just made of plastic. Its parts are molded from various types of composite-filled nylon that strike the perfect balance of rigidity and resistance to breakage. Traxxas has been perfecting the formula for years! We can't promise that you'll never, ever break something, but you can count on the T-Maxx for superior durability and you'll be amazed at the kinds of crashes and daredevil stunts it can withstand.
